Mean blood pressure ≈cardiac output × systemic vascular resistance (1) Thus a low blood pressure may be secondary to a low CO, low SVR, or both. Conversely a normal blood pressure can exist in the face of decreased CO if SVR is high. A low CO may occur for many reasons including inadequate vascular volume,
